How to get an overview of TYPO3's caching status? - caching

How can you find out which pages were cached when and how often? I'd like to use the Info Module to list it, if possible, as it seems to have been possible once with the extension cachemgm, at least according to a screenshot from the old documentation (this no longer works in the new version).

Where have SDL2 wiki examples gone?

In this video (https://www.youtube.com/watch?v=qPHKWsZK2Jc&list=PLvv0ScY6vfd-p1gSnbQhY7vMe2rng0IL0&index=10) from about a year ago, there is example code on the SDL_CreateWindow function documentation page. I have seen other posts talking about the SDL examples.
If you look at the documentation now it is the same minus the example code
https://wiki.libsdl.org/SDL2/SDL_CreateWindow
Am I blind or is there no longer any example code on the SDL2 wiki?
If not, does anybody know what the reasons for removing it are?
I expect that
There are some official examples somewhere
If they were removed from the official wiki they would at least be placed in a 'legacy' repo or something like that.
A Google (DuckDuckGo) search gives only third party examples and, aside from a few forum posts, no mention of there ever being any examples on the wiki.
In 2022, the Wiki migrated from MoinMoin to ghwikipp. With that came a host of breaks and bugs. Your issue specifically is covered under issue #233.
The images were also broken, but that issue shows a workaround for viewing the Wiki in working form: use archive.org on wiki.libsdl.org, not wiki.libsdl.org/SDL2 where it is currently hosted. This gives you your examples back.
e.g. like this
If you have some sort of MediaWiki viewer program, you can also just pull an old revision from the Repo and read it offline. Even Github's MarkDown viewer isn't terrible. Caveat that new changes won't be reflected.
They promise us that it will be fixed at some point, and they do seem to be working hard on it. The only hardfix is either to (a) wait, or (b) help them finish their migration.

Check if WM_PARENTNOTIFY is deprecated API?

According to docs WM_PARENTNOTIFY seems to be deprecated, this sounds unusual but if this is the case then what API does replace it?
WM_PARENTNOTIFY message
It's not deprecated, you just happen to hit a bit outdated link.
The most recent I believe is this one.
You seem to have gotten confused by the disclaimer on this documentation entry. There are two parts to it:
We're no longer updating this content regularly.
This refers to the documentation itself. It got frozen at some point, when Microsoft decided to change their documentation site for the n-th time (with n > 3). Though it's probably the second part that had you confused:
Check the Microsoft Product Lifecycle for information about how this product, service, technology, or API is supported.
Since this documentation no longer receives updates, there's no promise made as to whether the content still applies. It could (and generally is) still accurate, but it could be wrong or outdated as well, and you would need to check elsewhere.
That elsewhere is here: WM_PARENTNOTIFY. It would certainly be nice to have the old documentation auto-redirect to the new content (and sometimes this works, too, easily identifiable by a query string that contains the redirectedfrom=MSDN parameter). If in doubt you can identify up-to-date documentation by an Edit link at the top right corner.

Firefox source code analysis; lines of code per component

I am currently trying to analyse Bugzilla in order to find the ratio of number of bugs : lines of code for each Firefox component. However, I have never worked with Bugzilla before and have no knowledge of Firefox's codebase.
How would I go about finding lines of code per Firefox component (as they appear on Bugzilla under Comp header)? I have made an attempt at looking through mozilla central, but have no idea which source files relate to which components.
EDIT: Dexter pointed out that there is a directive BUG_COMPONENT in the mozilla-central tree, but this directive seems extremely incomplete and is not helpful. Any other advice, or pointers as to where I could get such advice would be much appreciated.
Great question! We recently added the BUG_COMPONENT directive (see the meta bug) to the Firefox code: it's in the moz.build file contained in each directory in the source. This directive allows linking each file in the repository to the related Bugzilla component.
For example, the following directive found here, tells that all the files in test/browser containing the Telemetry word belong to the Toolkit::Telemetry component on Bugzilla.
with Files("test/browser/*Telemetry*"):
BUG_COMPONENT = ("Toolkit", "Telemetry")
You can use either DXR or searchfox to quickly search the Firefox repository.
Updated the answer to account for the questions in the comments.
As noted in the comments, some components are tracked on Bugzilla (e.g. Activity Stream) but do not have a direct mapping to source files within the mozilla-central repository (the one Firefox is built from). That's because some newer components do not ride "the trains" (~6 weeks development cycle), but are rather updated more frequently and deployed as addons.
The code for these components usually lives under the Mozilla github account, along with other project. Since there are quite a number of projects, one way to identify the ones you might be interested in is to restrict them to JavaScript ones. If you follow this last link, you'll see the repository for both the test-pilot and Activity Stream (plus other addons).
I'm afraid the only way to match GitHub projects to Bugzilla components is to look at the name of the repository on GitHub and find the matching component in Bugzilla: you can type the name here to get some component suggestions. If you want to get fancy, you might also leverage the Bugzilla REST API:
Get a list of the JS GitHub project.
Extract the name of the project.
Use the REST API to get the component suggestion.
I would personally just consider the mozilla-central repository as a starting point, as it is mostly annotated: scrape the BUG_COMPONENT from the source files, map them to the paths then use the REST API to get the list of bugs.
Sidenote: the Download Panel seems to be correctly annotated in the main repo.

How to integrate Firefox Sync?

Firefox 4 comes soon (ok, next year ;)) and there is a Firefox plugin to sync your bookmarks etc. with Firefox 3.whatever .
I would like to know if anyone has a comprehensive, up-to-date tutorial to integrate Firefox Sync into your own plugin? Or any idea regarding this?
I mainly followed this official "tutorial" and also this blog post, but the information seems to be slightly outdated.
For example, the object is not called Weave anymore but Engines and the weave.engines. preference became services.sync.engines.. I played a little with all the mentioned options, but it does not seems to work (and my plugin does not show up in list where you can select what to sync).
I assume that the Tracker and Store classes are fine, the main problem is to register the engine...
The ClientAPI tutorial you mention is definitely the way to go. I updated it recently so if something's not working, please let us know so I can fix it in the docs. Wladimir's blogpost is definitely quite old and contains some outdated information. We will also make changes to some parts of the API in the upcoming beta releases, so be prepared for some flux...
The Weave namespace is still the canonical way to access Sync related APIs from UI code. It exposes components such as Weave.Service and Weave.Engines. You can import it via Components.utils.import("resource://services-sync/main.js"). If you want to implement your own engine, you'll have to import the actual underlying modules, though (all listed in the ClientAPI tutorial). The tutorial also describes how to register your custom engine implementation. Once it's registered, it won't automatically show up in the preferences UI, though. I suggest building your own UI that flips the services.sync.engine.YOURENGINE pref in your add-on's preferences.
Out of curiosity, what kind of data are you trying to sync?

What do I need to know to create Xcode project templates?

I know some of the tutorials for creating Xcode project templates, for example this one here: http://robnapier.net/blog/project-templates-364
This is the best one I could find. All others basically repeat the same info, or are no longer up to date, or worse tell me that even they don't know what they're doing. Possibly useful tools that are linked to here and in other places are no longer available.
I keep running into roadblocks, and would like to gather as much information as possible on the process of creating Xcode project templates. Info that is most importantly up to date (at least it must be relevant for Xcode 3 or higher).
For example, what I'd like to see is:
a description of the
TemplateChooser.plist and similar
plist files and what these options do
(in my case, once I add a
TemplateChooser.plist, my project
disappears from the Xcode project
template list)
how to create a project template that references another .xcodeproj (when I do that, the other .xcodeproj appears in the project template list even though it doesn't use the special naming convention)
processes that can be applied, for example is it possible to run a script during the creating of a project from a template? This would be useful to unzip certain files into the newly created project.
If you have the answer or suggestions to any of the issues above, I'd appreciate that. Otherwise any link to good Xcode project template resources would be highly recommended. Especially if there is an official documentation from Apple - I haven't found one yet which seems to imply that project templates are undocumented.
Have you seen these:
http://www.sodeso.nl/?p=895
http://www.codeproject.com/KB/iPhone/CreatingXcodeProject.aspx
If you say you have searched, I'm pretty sure you've already seen the links but these are the best resources I could find with my 'googlabilities'
You might try contact this guy - http://linkedin.com/in/mottishneor he has some related messages around the web
The links suggested by FX are also not bad at all!
There is indeed little XCode template info out there. What I have found of interest are the following links (I documented myself on the topic, but haven't yet gone any further):
a Google Code search reveals a few examples, but not much
in particular, I found interesting to look at the code provided by Three20; they have some basic examples, like here
referencing another project worked for me, so maybe you could open a specific question about that giving more details?
there is information scattered on the Apple mailing-lists
there is no official documentation from Apple, as is evidenced by the lack of results to this query
I'm sorry if this is not a Enlighting, concise answer. As you said, it's not well documented, and sources are all over the place. I just hope I could highlight some places to find information that your own searches might not have reached :)
I don't have a Mac anymore, so this is as much as I can give you without testing this myself. As far as I can tell, Xcode templates are undocumented by Apple.
This guy has some guides for messing with Xcode templates but the info is pretty sparse. My suggestion for working with templateChooser.plist is to try to only edit that file in the interface builder.
This guide is a good example of how to add a reference to another .xcodeproj. For the reason you were having trouble adding a reference to your project we probably need more information.
If you scroll way down in this doc you can that each template already includes a script called myscript.sh. This script will show up in the scripts menu for projects built with that template. That isn't quite as convenient as running scripts automatically, but it's better than nothing.
In conclusion, Xcode template documentation is a nightmare. It looks like there are a lot of powerful features there, but they are obscured because of lack of user friendlyness and because documentation lags far behind Apples updates of Xcode. It just doesn't seem to be a priority for them. I hope this helps.
